OIL-BURNER.

Specification of Letters Patent.

Patented July 12, 19211.

Application filed January 31, 1920. Serial No. 355,525.

To all whom it may concern:

Be it known that I, Ronnn'r PAPENDELL, a citizen of the United States, residing at Detroit, county of VVayn-e, State of Michian, have invented a certain new and useful Tmprovement in Oil-Burners, and declare the following to be a full, clear, and exact description of the same, such as will enable othersskilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a part of this speci cation.

This invention relates to apparatus for burning oil, and has for its object an improved organization of parts adapted to so act upon a quantity of relatively heavy 011 as to raise its temperature before ignition to a high point, as well as break it up into relatively small particles, which, mixing with the steam or hot air which has already served to heat it, projects these particles in a fine spray from a nozzle located adjacent the point where the combustion is to take place.

Figure 1 is a side elevational view of my assembled device.

Fig. 2 is an enlarged sectional elevation of the central portion of the device, where the oil is first acted upon by the steam.

Fig. 3 is a sectional plan, taken along the line 33 of Fig. 2.

Fig. 4 is a side sectional view taken from V the same position as Fig. 1.

Fig. 5 is a cross-sectional view, along the line 5-5 of Fig. 4.

A represents the shell or casing, within which is contained the oil chamber B, adapted to be fed, as through the passage C. The walls D of the lower part of this oil chamber are surrounded by the steam or hot air space E, into which steam or hot air flows from a suitable generating source through the valve-controlled passage F. The steam chamber E may becleansed and accumulation of sediment removed therefrom through the bottom vent G, and sediment may be removed from the oil chamber by opening the bottom passage C.

It will be noted that'the relatively small top portion of the oil chamber B communicates with the largest one of the three concentrically arranged discharge or spraying nozzles J, K and L, whereas themiddle nozzle K, extending one step farther back than the wall H is the rearward end of the smallest nozzle L, into which steam mayv flow when the controlling valve T is open. Each of these spraying nozzles being thus connected with an source of pressure, whether steam or hot air, and the first named and largest one J being also connected with a source of oil supply, there are provided plural sources of steam to mingle with the steam and oil particles which are coaxially delivered thereabout from the forward end of the largest tube or nozzle J. Considerable mingling of steam and oil particles, suiiicient in fact for some purposes, thus results from the action of the steam admitted to the oil chamber by opening of the control valve F. When, however, finer breaking up of the oil particles, and a higher projective velocity of the mixture is desired, one or both of the smaller nozzles K and L is brought into action by the opening of the respective conback in the-casing individually regulatable pension in the steam and more or less' thoroughly mingled therewith.

The extent of these nozzles forwardly to variant distances from the shell or casing, A, properly spaced from one another if desired, by the spider A, is shown particularly in Figs. 1 and 4. The outer end of the longest and largest nozzle J is capped by a centrally perforated spray regulator V, which is carried on the ends of the flanking and diametrically located slide rods U, the rear end of each of which passes slidably through the guide bearing X on the outer shell Y. The other two tubes K and L, which are of smaller diameter than the nozzle J and contained therewithin, are also shorter, so that the steam particles emerging from them pass through and mingle with the mixture from the nozzle J, and with it are controlled as to their escape from its end by this regulator V. e

A saddle Z is keyed to each of these slide bars, and from each saddle there extends rearwardly a link Z with a pivoted regulating lever Q, the lower end of, which straddles thenotched quadrant edge Q, so thatthe spring-held latch Q in the handle Q, frictionallyengages it to-hold the handle, and consequently its connected parts leading to and including the terminal V, which. are held in desired Yposition relatively to the projecting shell The operation of this device is as follows:

Being adapted to work upon heavy oilS, andatodeliver the same in finely broken up or dispersed shape bustion is to take place, it is desirable that the temperature of the oil as furnished to the oil chamber B, with which is connectedthe largest one, J, of the sprayingnozzles, be quickly and consistently raised to" a high degree, and: to this end' the steam chamber D is made to surround it, thus maintaining a body of live steam or hot air all about the lateralwalls B. The steam or hot air" is thus projected at a high velocity through theupper'portion ofthe chamber and across the top surface of the oilthat has risen thereinto, and in its through the large nozzle J, not only picks up thetop surface of the oil, but,asit carriesit forward, breaks the highly heated oil intov fine particles which lend themselves readily to combustion especially when supplemented by the actlon of one or both of the smaller nozzles K and L, when the point of-intended ignition is reached, this point being justioutside of the adjustable and centrally perforated terminal plate V. The exact. distance from this plate, may, however, easily vary to such a degree that, under some circumstances, the longitudinal projection of the mingled steam and oil particles straight out fromthe end of the nozzle will give the best:results. In suchcase, the handle Q is moved rearwardly (to the left as shown in Fig.- 1), so as to force theguide rods U for ward, and thus move. the centrally perforated plate V appreciably away from the capped end of the nozzle J In other cases,

however, combustion conditions may render it advisable to have the projection of the mingled steam and oil particles follow more or le'ssoblique lines from the continued central axis of the nozzle, as indicatedby the dot and dash lines at the extreme right end of Fig.7 4:. In this case the handle Q is thrown forwardly (to the dotted line position-shown in Fig. 1), thus drawing theslide rods U and their supported plate V closely againstthe end of the nozzle. J thusv reducing to a minimum the proportion of the mingled oil and steam particles which are which is connected at the point where conrrush forward to escape particles, is indicated at ends of the included large spraying nozzle J...

By its heatin influence thereonit increases the degree of vaporization of'the" already more or less mingled oil and hot air (or What I claim is W V steam) proceeding for m thgrethrough 1 from the shell A.
